If you were measuring the distance between the Sun and Proxima Centari, you could do it in millimeters and have accuracy to spare.Įven though I've run HPC simulations most of my career, we've seldom needed more than around six decimal digits of precision that's akin to variations of human hair width when working at the meter level. If you were measuring with a meter stick, you could be measuring the radius of electron charge radii with several precision bits left over. Intel's documentation change basically says you should scale and reduce your numbers first before running the functions.Ĭonsider what that level of error precision means. The issue is in sine, cosine, and similar trig functions, with an actual error of 4e-21. You might take a look at the article and at Intel's reply.
